Transport automation is increasingly being studied from different perspectives; however, the perceptions of road haulage companies have received less attention. This study explores views representatives small- and medium-sized on transport in Finland. We conducted an online survey to gather automation, which 254 responses a range industries. The respondents’ towards were generally negative. ove...
Improving Fuel Economy and Acceleration by Electric Turbocharger Control for Heavy Duty Long Haulage
Thirty healthy trammers were examined in underground haulage mines during their normal activity. Physiological strain in terms of heart rate (HR) varied between 101.6 and 104.7 beats/min with mean net cardiac cost of 33.06 and 34.06 beats/min for younger and older groups respectively. The average relative cardiac cost was lower for younger subjects than for older ones. Oxygen consumption (VO2) ...
The impact of fatigue is seen not only in its effect on job performance of haul truck operators but also on the health of the operator and the productivity at the mine site. Its impact can even extend outside of the mine site to the health and well-being of the surrounding community (Fourie et al., 2010). In this paper, a case study of a small surface mining organization is presented. The goal ...
The economic crises highlighted the importance of rethinking the operation of the transport sector. Companies, research institutes, governments and the society are all interested in smart solutions to reduce internal and external cost effects of road haulage via increasing efficiency and widening the utilization rate of available capacities along with the mitigation of social side effects of ro...
NIOSH researchers conducted a study to compare seat designs on underground coal mine haulage vehicles. The objective of the study was to support prior findings that NIOSH-designed seats, which incorporated ergonomic design features (e.g., viscoelastic foam padding and low-back support), are improved designs. Based on measured levels of vehicle jarring/jolting and perceived discomfort, researche...
